ABA Billing Services in Delaware: What Every Therapist Needs to Know

If you’re an ABA therapist in Delaware, you already know that billing isn’t just paperwork—it’s a crucial part of running a stable, sustainable practice. And yes, you’re not the only one who feels like managing billing requirements can sometimes feel more complicated than the therapy itself.

That’s exactly why this guide exists: to take the stress and confusion out of the equation. Whether you’re new to ABA billing or looking to fine-tune your current systems, this post will walk you through the most important things you need to know—without the fluff or filler.

We’ll dive right into Delaware’s credentialing rules, essential billing codes, reimbursement strategies, and the operational practices that make ABA billing services smoother and more profitable. 

Delaware’s Regulatory Framework for ABA Billing

Delaware’s insurance landscape comes with its own nuances. ABA practices must keep up with Medicaid regulations, secure authorizations whenever treatment plans shift, and follow each insurer’s specific documentation requirements—creating a maze that demands constant attention.

In Delaware, major payers—Highmark Blue Cross Blue Shield, Aetna Better Health, and Medicaid—each set their own billing requirements. For example, any change to a treatment plan often demands a fresh authorization, while some insurers insist on updated evaluations every quarter. When billing for group therapy sessions, additional paperwork is frequently required. Overlooking these nuances can easily lead to claim denials, so staying on top of each payer’s rules and keeping thorough documentation is essential.

Essential CPT Codes Every Delaware ABA Provider Must Know

If you're providing ABA therapy in Delaware, knowing the right CPT codes is crucial for getting reimbursed accurately. Here are some of the most commonly used billing codes in ABA therapy services:

• 97151: A qualified provider conducts the first behavior assessment to understand the client's needs and create a tailored treatment plan. 

• 97153: A technician provides individualized, one-on-one behavior therapy directly to the client.

• 97155: This code applies when a BCBA or another licensed professional provides oversight or makes adjustments to the therapy protocol.

• 97156: Parent training sessions with family guidance while client is present.

• 97158: Group behavior treatment.

Each of these codes is billed in 15-minute units and must align with the treatment plan, progress notes, and authorization limits.

  Accurate coding isn't just compliance—it's the foundation of consistent reimbursement.

Insurance Dynamics and Reimbursement Strategies 

Understanding insurance isn’t just part of the job—it’s a core strategy for running a successful ABA practice in Delaware. Medicaid tends to offer more predictable rates, especially for licensed psychologists, while private insurers vary widely. Many private plans cap ABA therapy at $36,000 per year for kids under 21, so therapists must plan treatment carefully. Pre-authorizations and eligibility checks aren’t optional—they’re critical. The key? Stay informed, stay organized, and work within each payer’s limits to ensure families get the care they need—and you get paid on time.

Common ABA Billing Challenges in Delaware

Prior Authorizations

Providers often find themselves caught off guard when an authorization expires, and sessions are no longer covered. With Delaware Medicaid and other insurers requiring specific re-auth timelines, tracking these dates manually is risky.

Solution: Use a billing system or partner with an ABA billing company that offers automated reminders for re-auth requests.

Claim Denials from Incomplete Documentation

In Delaware, insurance companies often reject claims when notes lack detail or don't match the treatment goals listed in the plan.

Solution: Standardize session note templates that include goal progress, behavior data, and intervention details. Conduct monthly internal audits.

Credentialing Delays

Whether you’re a solo BCBA or adding a new RBT to your team, credentialing with payers like AmeriHealth or UnitedHealthcare can take 60–120 days.

Solution: Use credentialing services familiar with Delaware to avoid revenue delays.This can save months of lost revenue.

Maintaining Compliance and Ethical Billing

Billing ethically isn’t just about avoiding fraud—it’s about protecting your practice and ensuring your clients receive the services they need without interruption.

Be HIPAA-Compliant

Choose software that encrypts client data and maintains HIPAA compliance standards. 

Bill What You Deliver

Never over-code or bill for services that weren’t performed. Keep your records clean, and when in doubt, under-bill and follow up with clarification. It’s not worth risking your license or reputation over an avoidable error.

Streamlining ABA Billing Operations for Optimal Efficiency

Understanding billing rules is important—but turning that knowledge into a smooth, efficient process is what really makes a difference. For ABA practices in Delaware, cutting through the paperwork and optimizing operations can be the key to lower stress and stronger cash flow.

What a Well-Run RCM Process Really Looks Like

Revenue Cycle Management (RCM) isn’t just about submitting claims. It’s a series of steps that, when done right, keep your revenue moving and your team focused. A strong RCM system includes:

• Real-time eligibility checks to avoid preventable rejections

• Active monitoring of authorizations to ensure services are approved in advance

• Prompt payment posting and account reconciliation

• Quick follow-up on denials, including appeals and resubmissions

Practices that maintain this level of organization often hit collection rates as high as 98%, well above the national average.

Credentialing Services: Laying the Foundation for Billing

Even before the first claim is submitted, proper credentialing lays the groundwork for financial success. This process verifies the therapist’s eligibility to bill under a payer’s plan.

In Delaware, common credentialing steps include:

• Submitting provider applications through CAQH

• Attaching licenses and certifications
